離心泵有(you)(you)很多(duo)(duo)不(bu)同的(de)(de)類型,對于不(bu)同液體(ti)(ti)需要選擇不(bu)同的(de)(de)離心泵,液體(ti)(ti)粘度不(bu)大(da)(da)、流(liu)(liu)(liu)量(liang)較(jiao)(jiao)大(da)(da)、揚程(cheng)不(bu)高時(shi),宜(yi)選用(yong)往(wang)復泵;液體(ti)(ti)粘度較(jiao)(jiao)大(da)(da)、流(liu)(liu)(liu)量(liang)較(jiao)(jiao)小(xiao)、揚程(cheng)不(bu)高或(huo)(huo)(huo)(huo)含(han)有(you)(you)氣泡(pao)時(shi),可(ke)選用(yong)旋(xuan)渦(wo)泵;液體(ti)(ti)粘度較(jiao)(jiao)大(da)(da)、流(liu)(liu)(liu)量(liang)較(jiao)(jiao)小(xiao)、揚程(cheng)較(jiao)(jiao)高時(shi),宜(yi)選用(yong)轉(zhuan)子(zi)泵。 理解(jie)類型的(de)(de)選擇是(shi)最基(ji)本的(de)(de),只(zhi)有(you)(you)正確(que)選擇才能使得正常運(yun)轉(zhuan),但(dan)是(shi)我們(men)在(zai)使用(yong)中經常會遇(yu)到(dao)突然泄(xie)漏的(de)(de)問題,這又是(shi)哪些(xie)原因造成(cheng)的(de)(de)呢?下面就來(lai)分析一下。 1、抽空、氣蝕或(huo)(huo)(huo)(huo)較(jiao)(jiao)長(chang)時(shi)間憋壓,導(dao)致密封(feng)破壞(huai); 2、對泵實際輸出量(liang)偏小(xiao),大(da)(da)量(liang)介質泵內循環(huan),熱量(liang)積(ji)聚(ju),引起(qi)介質氣化(hua),導(dao)致密封(feng)失效; 3、回流(liu)(liu)(liu)量(liang)偏大(da)(da),導(dao)致吸(xi)人管側容(rong)器(qi)(塔(ta)、釜、罐、池)底部沉渣(zha)泛起(qi),損壞(huai)密封(feng); 4、對較(jiao)(jiao)長(chang)時(shi)間停(ting)運(yun),重(zhong)新起(qi)動時(shi)沒有(you)(you)手動盤車,摩擦副(fu)因粘連而扯(che)壞(huai)密封(feng)面; 5、介質中腐蝕性、聚(ju)合性、結膠性物質增(zeng)多(duo)(duo); 6、環(huan)境溫度急劇變(bian)化(hua); 7、工況頻繁變(bian)化(hua)或(huo)(huo)(huo)(huo)調整; 8、突然停(ting)電或(huo)(huo)(huo)(huo)故障停(ting)機等。 當遇(yu)到(dao)突然泄(xie)漏的(de)(de)問題,我們(men)一定要正確(que)分析,以采取對的(de)(de)措(cuo)施,以免造成(cheng)不(bu)要的(de)(de)損失。

水環真空泵一直非常關注粗糙真空的獲得,例如真空過濾,真空水轉移,真空蒸發等。它已廣泛用于工業生產的許多過程中。 為了節約能源,有必要盡可能地節約能源。我們如何使用水環真空泵來節能? 1. 水環真空泵對角安裝,以減小彎頭或蝸殼,使水口面向水池。 2.縮短水環真空泵管道,拆除1米長的鋼管,并在10小時內節省0.21千克柴油。 3.擴大水環真空泵的出口管直徑。例如,將15米長的4米長水管替換為15厘米長的管道,并節省10公斤柴油10小時。 4.如果可以保持進水清潔,?
